Chacha joins HXEROS as a new member and starts living with the team in the same dormitory. Chacha enters Retto’s consciousness to find the source of his H-energy. While still merged with Retto’s consciousness, she visits the rooms of Maihime, Momoka, and Sora and stimulates their H-energy. She ends up taking a bath with Kirara, which makes Retto antsy. Chacha’s powers are too much for Kirara, who faints from the heat. Chacha realizes that Retto is in love with Kirara and takes control over his body while whispering to him that now is his chance.
And once she says something,
there's nothing I can do to stop her.
Zumal man sie nicht aufhalten kann,
wenn sie sich was in den Kopf gesetzt hat.
Y una vez que dice algo,
no puedo hacer nada para detenerla.
Mais rien de ce que
je pourrais dire ne l’arrêtera…
E quando ela decide,
não posso fazer nada para impedi-la.
